      @mitu maybe we should add an additional emulators.cfg option for cassettes? If there's no way of handling it from one command line - what do you think?

      I've not used this emulator much beyond some testing some time ago.

        Although would that mean 4 more launching options for each system we have? As that makes me think upstream needs an automatic mode, which could be requested maybe

          @buzz Didn't test any .cas options when the module was redone (based on @JenGun's fork), but I can take a look to see if it has any automatic media detection and maybe update the launch options or find a option to accommodate more media types.

            @mitu Sounds good. Feel free to pass anything my way also. Cheers.

              The option for loading cassette images is -cassette or -cass ...

                Automatic media detection for a few use cases? Probably not ... :-)

                  Swapping -flop1 in EMULATORS.CFG for -cass has got me to the OS, many thanks to all. Now when I type CLOAD the tape counter appears and runs, but nothing happens when it reaches the end :(

                    Loading programs from cassette was always a pain in the "old days" because it depended on various factors: volume of the recording and quality of the tape ... and mostly only succeeded by chance ... ;-)
                    You can only load BASIC-programs with CLOAD, for programs in "machine-language" use SYSTEM ...
                    Not all CAS-files of the internet will work in the emulator ... so please provide more details ...

                      Don't know if it will work on TRS80 but with MSX you had to do :
                      cload
                      run

                      You can try that.

                        @folly I don't get the command prompt back after the load.

                          @jengun @jengun Okay, so I'm trying to load SeaDragon, as seen here:

                          That video shows the game is loaded with SYSTEM followed by S, and if I do that then the tape spins up and loads for about four minutes. But after that nothing happens and I'm just left looking at this:

                          seadragon.png

                          I'm still getting nowhere with SDLTRS, so I'm using LR-MESS:

                          lr-mess-trs-80-cass = "/home/pi/RetroPie-Setup/scriptmodules/run_mess.sh /opt/retropie/emulators/retroarch/bin/retroarch /opt/retropie/libretrocores/lr-mess/mess_libretro.so /opt/retropie/configs/trs-80/retroarch.cfg trs80m3 /home/pi/RetroPie/BIOS -cass %ROM%"
                          
                          

                          I'm just hitting Enter when the "Cass?" and "Memory Size?" prompts come up. And as I said it's the CAS file from the most recent MAME softlist so hopefully it's not the file that's the problem.

                          Raspberry Pi 3b and 8GB Raspberry Pi 4, both running Retropie 4.7.1 installed from scratch using Raspberry Pi Imager, with wired keyboard, wireless mouse and double arcade joystick attached.

                            No idea which CAS-file MAME is using, but this works with SDLTRS in Model I-mode ... in Model III-mode you have to type L after Cass? to select 500 Baud to load and save tapes for the Model I ...

                              You can only use .wav (cas files) with TRS-80 (trs80) on mame/lr-mess.

                              This is the output from mame :

                              pi@raspberrypi:~ $ /opt/retropie/emulators/mame/mame -listmedia trs80

                              trs80            cassette         (cass)     .wav

                                SDLTRS also supports WAV-files (mono) as cassette images, so that should work too ...

                                  Job done! That generated a flickering asterisk readout at top right, and got the command prompt back when the tape was finished, then I watched the video to find out you need to (bizarrely) type / to start the game.

                                  Many thanks! Now I just need to get sound working...

                                    On the internet I see info of people using (binary files) :
                                    CLOADM

                                    You could try that.

                                      I see / doesn't work for EVERY game, so time to do some Googling. But other than sound that's the emulator figured out now, which is the hardest bit :D

                                        Yeah, I'm quite experienced with the Dragon/Coco so CLOADM was the first thing I tried, but I'll keep it in mind for other filetypes :)

                                          For these TRS-80 Models there is only CLOAD and SYSTEM ... no CLOADM ..

                                            @jengun Is there any significance in the fact that the asterisk readout sometimes starts with a C rather than being all asterisks? Those seem to be the games that can't be started with /.
